Key Points

  • Yes, you may still become pregnant if you are using Lupron Depot. Lupron Depot is not a method of birth control. Even though you may not have a period, unprotected intercourse could result in pregnancy.
  • You should use non-hormonal birth control such as condoms, a diaphragm with contraceptive jelly, or a copper IUD to prevent pregnancy while you are using Lupron Depot. Talk to your doctor about use of birth control before you start treatment.
  • Lupron Depot may also cause harm to an unborn child. Do not take Lupron Depot 3.75 mg and 11.25 mg if you think you are pregnant or think you may be pregnant, or if you have undiagnosed uterine bleeding. Talk your doctor immediately if you think you may be pregnant.

Your doctor will give you a pregnancy test before you start treatment if one is needed.

It is classified as a gonadotropin-releasing hormone (GnRH) and works by lowering the amount of estrogen in women and testosterone in men.
